I don't think lack of articles submitted is a problem. What's wrong with lurking and posting a few comments here and there to gain the karma needed for posting? Another idea is that posting one article a day could be free, but ti costs karma for each additional one posted (maybe even an increasing cost based on how many you post per day.)
